step S1: prefabricating an H-shaped steel column in a factory, simultaneously arranging a plurality of connecting holes on the inner side flanges of the corresponding positions of the H-shaped steel column according to the requirement on the storey adding height, and welding two L-shaped right-angle buckles on the flanges of the upper end and the lower end of the H-shaped steel column;
step S2: manufacturing prefabricated unit modules in a factory: assembling the H-shaped steel column, the H-shaped steel beam and the top floor slab into a cuboid frame unit through welding or high-strength bolt connection, and pouring concrete on the top floor slab;
step S3: manufacturing a prefabricated corridor floor and a prefabricated interlayer floor in a factory;
step S4: the manufacturing of the beam connecting piece, the same-layer column connecting piece, the different-layer column connecting piece and the partition board connecting piece which are required are completed in a factory;
step S5: the installation of the prefabricated interlayer floor system is completed in a factory: connecting the prefabricated interlayer floor with the H-shaped steel column of the prefabricated unit module through a partition plate connecting piece and a high-strength bolt;
step S6: the prefabricated unit modules which are manufactured and installed are transported to a construction site, the splicing of adjacent prefabricated unit modules on the same layer is completed on the site through beam connecting pieces and column connecting pieces on the same layer, and the splicing of adjacent prefabricated unit modules on different layers is completed through column connecting pieces on different layers;
step S7: the installation of the prefabricated corridor passageway and the prefabricated corridor floor is completed on a construction site, and gaps among the floors at the top of the same floor are filled with micro-expansion high-strength concrete;
step S8: repeating the steps S1-S7 until the whole project is completed.
